Oh my heavens this cake is moist! Like heavenly moist & delicious! I was a little nervous that it was just pumpkin without any pumpkin pie spice added to it, but it doesn’t need it.

It’s so sweetly pure & delicious. It practically melts in your mouth because it’s so moist & it’s incredibly hard to just eat one piece. Hooray for Fall & pumpkin baking! This recipe is a keeper!

You need to make this now…like YESTERDAY! But make sure you can share it with friends because it makes a lot & it’s frowned upon if you eat the whole sheet cake to yourself. 🙂
